15 or 30 minute Far Infrared Sauna Sessions. 2-person size and Certified Low EMF carbon far infrared with 2 Chromotherapy Lights. While traditional saunas rely on humidity to heat the room around you, infrared saunas heat your body directly by emitting wavelengths of light that you immediately absorb. Localized heat sent to the source means tolerable temperatures and a quicker, deeper sweat. Infrared sauna therapy promotes relaxation by helping to balance your body’s level of cortisol, your body’s primary stress hormone. The heat generated by the sauna helps relax muscles and relieve tension and stress throughout the body.
